Congratulations on your purchase of the Gentner PA870, an 8-channel
power amplifier. This manual is designed to help you install and operate
your new amplifier.
The PA870 can power 8 Ohm and 70 Volt speaker systems
simultaneously (it comes configured for 8-Ohm operation from the
factory). This expands the amplifier’s versatility by opening up a wide
range of application possibilities, discussed in the Applications chapter
on page 11.
The PA870 delivers 25 watts (at 8 ohms and 70 volts) of power to each
of the eight channels. It also allows bridging in an 8 Ohm, one-channel
input/two-channel output configuration for 50 watts of power. Bridge
switches simplify bridging setup and protect against damaging cross
connections. Four LEDs indicate bridging status. Presence and clip
LEDs on the front and back panels notify you of signal status and help
you minimize clipping.
The PA870 requires just two rack units of space, so it conveniently fits in
a small space that requires multiple channels of amplification. Passive
cooling keeps the PA870 operating quietly.
If you have questions about the installation or use of the PA870 which
aren’t answered in this manual, please contact us at:
